BURN ER-.FASTENING FOR LANTERNS.

SPECIFICATION forming part ef Letters Patent No. 464,496, aerea December s, 1891. i

Application led March 29, 1 8 90.

To all whom it may concern,.- g

Be it known that I, FREDERICK Drnrz, a citizen of the United States, residing at New York, in the county and State of New York,

have invented a new and useful Improvement in Burner-Fastenings for Lanterns, of which the following is a specification.

This invention relates to the fastenings whereby an unthreaded or slip burner is secured in the socket of the oil-pot, and has for its object to provide a fastening by which the burner can be tightly secured in the socket to hold the burner securely in place and prevent leakage of oil.

.In the accompanying drawings, Figure l is a sectional elevation of the lower portion of a tubular lantern provided with my improved burner-fastening. Fig. 2 is a horizontal section on an enlarged scale. Fig. 3 is a fragmentary sectional elevation of the springfastening and connecting parts. Fig. et is a Fig. 5 is a horizontal section showing amodied construction of the fastening. Fig. 6 is a fragmentary sectional elevation of the same.

Like letters of reference refer to like parts in the several figures.

A represents the oil-pot of a tubular lantern, and B the unt-hreaded burner-socket secured in the top thereof.

C represents the annular air-Chamber surrounding the-socket, and D the air-tubes connected with the air-chamber.

E represents the burner, having its lower Unthreaded portion or Collar constructed to iit snugly in the socket B.

F represents the burner-cone, which is frequently made detachable from the burner, and H represents the perforated plate, which rests on the cone and supports the globe.

I represents the wick-raiser shaft, which penetrates the burner and projects, preferably, on opposite sides therefrom. The short projecting portion of the shaft is arranged within the air-chamber, while its longer portion, to which the hand-wheel is secured,pro jects through a slot h in the air-chamber.

J represents abow-spring secured centrally to the inner side of the air-chamber, as represented in Figs. 2 and 3, and provided with Serial No. 345,876. I (No model.)

looking ends j, which engage over the wickraiser shaft on opposite sides of the burner. These ends are bent upwardly from the main portion of the spring, as shown at 7a, then forwardly, as shown at Z, and then downwardly and back under the raised horizontal portions Z, as shown at m, thereby forming raised elastic arms having enlarged ends, the lower sides of which incline upwardly toward the upright portions 7o. The locking ends are turned in 6o opposite directions, as represented in Figs. 3 and et, so that the wick-raiser shaft can be engaged underneath the same by a short turning movement of the burner in its socket. Upon placing the burner in its socket with the wick-raiser shaft opposite the ends of the spring-arms and giving the burner a short turn inthe proper direction to move the wickraiser shaft underneath the ends of the fastening-spring, the wick-raiser shaft engages 7o under the locking ends of the spring-arms and defiects the same upwardly. When the wickraiser shaft has passed beyond the lowest portions of the enlarged ends of the spring, thc downward pressure of the spring holds the shaft against backward movement and seats the burner tightly in its socket. The e1as ticity of the spring compensates for any irregularities in workmanship, so that a close tit of the burner in its socket is obtained in all 8o cases. 1

Instead of securing the bow-spring to the air-Chamber at its middle, as represented in Figs. 2, 3, and 4, it may be secured near its ends, as represented in Figs. 5 and 6. In the 85 last-named construction the elasticity of that partIof the springwhich lies between the fastenings is not utilized. The elasticity of the spring-arms themselves is, however, in most cases sufficient to produce the desired effect. 9o In this modified construction it is desirable to form the two spring-arms in one piece, as shown, because it simplifies the construction and effects a stronger and more durable connection with the air-chamber.

It is obvious that a single spring-arm may be used for engagement with the wick-raiser shaft on one side of the burner; but this construction is less desirable, because it is liable to tilt the burner.

IOO

I claim as my inventionl. The combination, with the oil-pot provided With a Slip-socket, a burner capable of rotative movement in said socket and provided with a laterally-projecting wick-raiser shaft, and the air-chamber surrounding the burner, of a horizontal spring-catch secured to said air-chamber and adapted to engage ovei` the Wick-raiser shaft, whereby the burner is locked by turning it in its seat, substantially as set forth.

2. The combination, with the oil-pot provided with a slip-Socket, a burner provided with a Wick-raiser shaft, and the air-chamber surrounding the burner, of a horizontal spring,r secured in said air-chamber and having its free end bent upwardly and forwardly and back underneath the forward bend, forming FREDERICK DIETZ.
